Properties of Multiplication

Properties of Multiplication: Learn

There are four mathematical properties which involve mutliplication.
The properties are the commutative, associative, identity and distributive properties.

Commutative Property: When two numbers are multiplied together, the product is the same regardless of the order of the multiplicands.

For example 4 * 2 = 2 * 4

To remember the commutative property, it might be helpful to think about the
word commute which means to switch places between home and work
(or home and school). In the example above, you can see the 4 and the 2
commuting or switching places.

Associative Property: When three or more numbers are multiplied, the product is the same regardless of the grouping of the factors.

For example (2 * 3) * 4 = 2 * (3 * 4)

To remember the associative property, it might be helpful to think about the
word associate, which as a verb means to interact with a group (maybe
you associate with a certain group of friends!). The parentheses are
grouping operators, that is, they form groups of numbers and
operations. You can see in the example above, the 3 can associate with
either the 2 or the 4, but the value of each side is still a product of 24.

Identity Property: The product of any number and one is that number.

For example 5 * 1 = 5.

To remember the identity property, it might be helpful to think of it as a question
and answer: What number can I multiply by so that the value is not changed? One.
In the example above, the 5 gets to keep its identity because multiplying it by
one does not change its value.

Distributive Property: The sum of two numbers times a third number is equal to the sum of each addend times the third number.

For example 4 * (6 + 3) = 4*6 + 4*3

The distributive property is the only property that combines multiplication and addition.
That makes it very important!
